7 My invention relates toimpriove dlmeans by whicha rotary. cutter head may besecurely held 7 while the several cutters. thereof are successively and properly sharpened by a hone manually operated-[in the usual manner. One objectof the invention is to construct such aholding device that it maybe .detachably connected with two of the projecting cutters or blades offthe headwith out in any way interfering with-the proper application ofthehoneto.the cuttingiedge v of one of the-othericuttersr w M A' further important object of the invention is toprovide a holdingldevice'whichwill accurately and securely holdthecutterhead V V cated' in Flg. 1,.and the lower portionof this in properposition for the sharpening: of cut;

ter blades associated.withthe, head, -without requiring any manual adjustments of the: holding device. 7

Another and quite important object of the invention is to so construct the device that the direction of movement'of thehone cannot, bycarelessness orinattention on the part ofthe workmambe so changed as to tend to destroy or impair the necessary bevel across the outer face of the lower end of the cutter, such'for example as the bevel shown at ('13) in the LettersPatent No. 1,522,145, granted marily designed to be used with.-

The above objects I accomplish by the construction and arrangement shown in the.

. drawing and hereinafter more particularly described. That which I believe to will be set forth in the claims.

In the drawing: Fig. 1 is atop'or be new '-.45 ened,the bar-shaped handleof' the imple ment being partly broken away; i

Fig. 2 is a view of the same parts as in Fig. 1, but showing an edge view of the'hone guide.

xFig.,,5 is across-sectionthroughthe bone 7 and its frame.

Referring to the severahfigures or the drawing wherein corresponding parts are indicated by'the'same reference characters, (10 indicates a rotary. "cutte'rlhea'd that jis preferably of the same general'type shown and described inmyaforesaid Letters Patent;

AS here shown itisprovided with four-blades pr; cutters (11) set- .90 T degrees apart and beveled in the usual manner,as clearly-indiadapted? to beproj'ected and heldjby any suit a ,ablemeans. The outer end of each blade is beveledend is additionally beveled as, indi;

cated at 12)in Fig.2, such additional bevel in g alsofinclining' upwardly; from front to.

acter shall notbede'stroyed or impaired.

7 As best'shown in 3, the sharpening ,plement .that ha's been referred to comprises) -objects of 'the invention to ensure that in the use of the: sharpening implement :its char-- ajhone (20) secured inganyappropriateinanher in a'fra me and provided'at' oneend Iiv-ith a comparatively long handle (22) which,

in the form here showmis a cylindrical"bar.

g The guiding devicefor the sharpening im plementcomprisesfa base (30.) thatwill pref I Ierably'bemade of a single piece ofsheet met- 'al.v ,At one end thereof are-formedtwo spaced bent upw ardly from the end of :the base or plate, 'andat' some;distancev therefrom", and preferably cutand punched from and integral with the base are two other "andsimilar ears V apart ears, (31%3 1) thatstand'atright angles V y g V tothe' base, said'fejars being integral with and plan view ofmy .40 proved hone guide connectedwith a-rotary 1. 9

1(32-32),athefdistance between these'two airs of ears'being sufficie'nt to allow ahead such as (10) to fit snugly between-them; These two pairs of ears:"constitute seats .for

the reception of'a pair of the projecting cut- Y; ears is just wide enough to receive one "of' ters- 11 without necessitating any manual ad- I V justments." "The spacebetween each lpairxof T1 00 the base (30) is turned to form a flange (33),

that extends in the opposite direction from that of the ears. This flange is also extended laterally from the base, 30-) and in its outer end is formed a comparatively deep notch, (BA) in which the handle member (22) of the sharpening implement, is adaptedto be movably mounted. pf-

In use, a head (10) is to be placed between the tWo pairs of ears (31) and (32) with two of its oppositely-located cutters holding it there by reason of their entrance into the spaces between the two pairs of ears. The workman will then ordinarily hold the cutter and base'in one hand, in approximately the position shownin Fig. 2, which will. bring the cutter (11) that stands parallel'witlrthe base flange (33) in convenient position to have the hone applied to it. Before applying the hone, the handle member .(22)is placed in the notch (34), such notch being large enough not to interfere in any way with the application ofthe hone to the cutterfe ither by a lengthwise or sidewise movement of the hone or by a combination; of such movements. The extension of the fiangelaterally, how-- ever, in. the same direction as the cutter that is being sharpened, and theengagement by the bar (22) of the notch in that flange, absolutely prevents the hone from being so directed as to impair the small additional'bevel (12) that is soimportant to the performance of proper work by the cutter. By reason; of the handle bar being so held'against being shifted bodily to a position opposite the base :(30) the movement of the hone, when operating nponthe bevel portion of the cutter must bein the general direction of that bevel, as will be made clearby an inspection of Fig. 2.

WVhat I claim as new and desire to secure by Letters Patent is as follows:

1. A device of the character specified comprising a base, spaced seats on thebase into which a plurality of cutters that project from a cutter-head are positioned to prevent movement ofithe cutter-head relative to the. base,

and means carried by said base for movably ing a plurality of cutter blades, comprising a base having sharpening device guide means, and spaced pairs of lugs bent out from said base and adapted to be arranged upon opposite sides of said head, the lugs of each pair being spaced apart to receivetherebetween ablade of'said head and being arranged to receive and hold said 'head against movements inducedby the sharpening operation.

.5; A device of the character described comprising'a single sheet of material having a pair of spaced apart angularly disposed lugs struck out therefrom, a second pair of spaced apart angularly disposed lugs formed from one end of said sheet and spaced from said firstpair of lugs, and the opposite end of said sheet of materialhaving an angularly dis flange formed therefrom.
